Page 5 - Conclusion and scoring

Now we come down to scoring the Platimax in four categories: performance, build quality, functionality and value.

Performance (40% of the final score) - The Platimax is a great unit, but peppered with a few disappointments. The voltage regulation could really use some help. Not only the non-primary rails, but the +12V and +5VSB as well, which seemed to get worse as temperature got higher. Efficiency was fantastic, although it would be nice to see the unit actually hit 80 Plus Platinum at 100% load. The ripple suppression was perfect and the Platimax passed the overshoot and rise time tests. Given these results, I'm giving the Platimax a performance score of 8.

Build Quality (20% of the final score) - There's not much bad I can say about Enermax's build quality. The design is innovative, the components used are top notch and the actual craftsmanship of the assembly is fantastic. Build quality score is 10.

Functionality (20% of the final score) - With it's compact size and full modularity, there isn't a bad thing I can say about the Platimax. There are plenty of cables and connectors to go around and everything you could possibly need, nylon bags for the cables, a cord keeper, Velcro straps, are all included. Functionality score is 10.

Value (20% of the final score) - Currently, the Platimax 1200W is on Newegg for $319. While it's hard to say if that's a decent price for an 80 Plus Platinum certified 1200W power supply, since there aren't any other 80 Plus Platinum certified 1200W power supplies available in the U.S. yet, it is quite expensive for a 1200W. It's even $40 more than the 80 Plus Gold certified MaxRevo 1200W. Although I believe that there is a price premium for higher efficiency, how much should that price premium be, and should it be far beyond the point of diminishing returns and your electric bill. Also, I can't help but to point out that it seems we have been sacrificing some performance, albeit well within specification, for slightly higher efficiency. For value, I'm giving the Platimax a score of 7.

Build Quality

Total Score


The Platimax is very efficient, fully modular, has great ripple suppression and is of excellent build quality. Unfortunately, it's also expensive and there is real room for improvement of the voltage regulation. Over all, the Platimax is certainly one of the finest 1200W power supplies we've reviewed and certainly should be a consideration if you're in the market for such a beast, especially if you can get one at a lower price or if some promotions start popping up that can help sweeten the deal.

The Good:

  • 80 Plus Platinum efficiency (almost)
  • Excellent ripple suppression
  • Excellent build quality
  • Fully modular
  • Plenty of cables and connectors
  • Comes with "bonus" 140mm fan
  • If we still graded aesthetics, I'd give this unit a 10 just for the platinum colored trim around the fan

The Bad:

  • Below average voltage regulation
  • Very expensive

The Mediocre:

  • Standard mounting screws instead of thumb screws
